Dead Rising 2 Case Zero came out a few weeks ago for 400 exclusively to the Xbox 360. Case Zero was presented as a sort of extended demo, prequel of the game where you get to keep your stats for the full game, as well as giving players a taste of how the weapon creation will work for the game. Case Zero also broke records for sales on XBLA in the first week, and has kept fans sated until Dead Rising 2's retail release in 2 weeks.
